JNTU B.Tech III SOFTWARE TESTING METHODOLOGIES Previous Question Paper (May - 2019 - R16)
Note: This question paper contains two parts A and B. Part A is compulsory which carries 25 marks. Answer all questions in Part A. Part B consists of 5 Units. Answer any one full question from each unit. Each question carries 10 marks and may have a, b, c as sub questions.
Part A
List any two goals of software testing.
Answer
Two primary goals of software testing are to identify defects in the software before it is released and to ensure that the system meets the specified functional and non-functional requirements.
State at least two differences between verification and validation.
Answer
Verification focuses on ensuring the product is built correctly according to specifications (Are we building the product right?), whereas validation ensures the product meets the user's actual needs (Are we building the right product?). Verification typically involves static techniques like reviews and inspections, while validation involves dynamic testing techniques.
